Using tetris in this way is really clever, but I think there should have been a small tutorial section in the game, honestly when we start the game directly I couldn’t really understand what I was supposed to do, I tried to figure things out by experimenting, the game actually looks really nice at first glance, you managed to bring together many mechanics within this limited time, still I think you should give the player a bit more hints, thank you for bringing such an interesting idea to life
